Demystify of Azure Function Apps

Cloud has changed the digital world and it gives a new way of digital transformation.  On premises stuff have been reached to hybrid, multilayer and type of cloud.  It has pioneered a new way of software design, developing, deploying and messaging our server and business solutions. The application hosting and execution platform includes a new concept called Serverless computing.

Serverless computing is nothing, it is cloud computing execution model which cloud provider allocates machine/applications resources on demand without having manage servers.

Azure Function Apps is a serverless computation service provided by Microsoft that can run code in response to predetermined events or conditions. It is one of the most popular services in Azure. They provide the ability to run pieces of code that are triggered by events or schedules. It automatically manages all the computing resources that those processes require.

Azure Function Apps is an event-driven serverless compute platform which is available on-demand and completely managed.

Advantages:
  • It can schedule or trigger by events.
  • Less code, but it supports the multiple languages.
  • Less cost, it pays per function execution.
  • Parallel execution when multiple triggers occur.
  • It supports Continuous integration/Continuous deployment.
  • It integrates easily with other Azure services and third parties services.
  • Open source.
  • Run anywhere 
  • Microsoft provides intuitive and browser based interface.

Azure Function Apps Usages:

  • To run a discrete small unit of code.
  • Schedule Tasks and Messaging
  • For notification or reminder generation
  • Files Processing
  • backend calculation
  • Lightweight API
  • event or data processing
  • Real time stream processing

Azure Function Apps Architecture:

Despite the serverless nomenclature, it does not mean that it runs without a server. Serverless is a new concept for the cloud world which is built on top of PaaS. It hides VMs, application frameworks and external dependencies through bindings so that developers can focus only on the code to implement the business logic.

Language Runtime: It runs scripts, executes libraries and hosts the framework for target language.
WebJobs Script Runtime: It provides the host, dynamics compilation and others to Azure function.
WebJobs Core: It provides an execution context for the function app.
WebJobs Extension: It writes background processing code that runs Azure WebJosb.
App Service Dynamics Runtime: It defines the technology stack that Azure uses to develop functionalities apps such as hosting, CI, deployment slots, remote debugging, etc.

Conclusion:

The emergence of the cloud provides a new definition of software service and Azure Function Apps is one of the popular choices. It offers the advantage of serverless which motivates the developer to focus on business solutions and code. Use-by-use payment model is a very cost-effective solution in the modern digital transformation where there is no need to manage or spend hardware and software. Azure Functions is billed based on resource consumption and execution per second.

PCF vs. Web Resources: Choosing the Right Extensibility Tool for Dataverse

Image
Extensibility refers to the ability to be extended or augmented beyond the default capabilities of the platform. This involves customization but also includes more advanced techniques, such as coding, integration with external services, and the use of custom components. In the context of Power Platform and Dynamics CRM, the term "extend behavior" refers to the ability to customize and extend the functionality of the platform to meet specific business needs. Extensibility often requires technical skills, such as coding in JavaScript, C#, or using tools like Azure Logic Apps and Power Automate for complex integrations. Customization  is a subset of extensibility. Customization involves configuring and modifying existing elements within the platform to suit specific business needs. Extensibility, on the other hand, covers a wide range of functions and techniques, including customization and more advanced development and integration tasks, to extend the capabilities of the Power

Is Debt Prosperity or Trap?

 “What can be added to the happiness of a man who is in health, out of debt, and has a clear conscience?”  Adam Smith Grandfather Bhishma lay on the bed of arrows and was preaching the future king of Hastinapur about political science, economics and the duties of the king. He took a deep breath and told Yudhishthira " Fire, debt and enemies must be dealt with quickly and completely. If there is any balance left, they can continue to grow. " The future king was listening with curiosity and was eager to learn about the complete knowledge from his grandsire. Each moment was important as the sun was moving from south to north. Either we read the quote of the father of modern economics or both ancient great scholars are advising to avoid debt. But the whole of modern economics is based on the debt that advises the public to borrow money. The aggressive campaign of banks and financial institutions has been luring more and more loans. Even democratic governments and public banks con
